A vehicle seat assembly is provided with a seat bottom that is adapted to be mounted to a vehicle floor. A seatback is adapted to be pivotally mounted adjacent to the seat bottom. An actuator is in cooperation with the seat bottom or the seatback. A controller is in electrical communication with the actuator and programmed to receive input indicative of a potential vehicle impact. In response to receiving the input indicative of the potential vehicle impact, the controller outputs a signal to the actuator to tilt the seatback, or to tilt the seat bottom.

A vehicle seat console has at least one vehicle-mounted guiding element, at least one seat-mounted guiding element that runs parallel to the vehicle-mounted guiding element, and a longitudinal adjustment mechanism on which a driving device acts via a transmission mechanism and which is designed to cause a relative adjustment between the vehicle-mounted guiding element and the seat-mounted guiding element. The vehicle seat console is characterized in that the longitudinal adjustment mechanism and/or the transmission mechanism is/are equipped with at least one energy absorption device which is configured to dampen abrupt relative movements between the vehicle-mounted guiding element and the seat-mounted guiding element.

To reduce the weight of a cross member bridged between right and left sides of a seat frame. A seat frame includes an upper frame forming an upper portion of a seat back frame, and a cross member bridged at the upper frame. The cross member includes right and left end portions in a seat width direction, the right and left end portions being fixed to the upper frame; and a first recessed portion that is recessed upward or downward and provided between the right and left end portions. The first recessed portion is provided at a center portion of the cross member in the seat width direction.

An impact absorbing device for a vehicle seat includes: a first base member; a second base member; and an impact absorbing member. The first base member rotatably supports the second base member. The impact absorbing member includes: a first fixing portion fixed to the first base member; a second fixing portion fixed to the second base member; and a deformable portion. The deformable portion is provided between the first fixing portion and the second fixing portion, and is configured to be bent by the rotation of the second base member. A distance between the first fixing portion and the second fixing portion in an undeformed state of the deformable portion has a value intermediate in a range of variation of the distance that varies depending on the bending of the deformable portion.

A seat backrest includes right and left side frame segments, a pressure receiving member disposed between the side frame segments movably in a front-back direction, and a cushion pad covering the front of the side frame segments and pressure receiving member. The pressure receiving member includes a main body part, and extending parts extending laterally from both sides of the main body part. The cushion pad includes a back receiving part covering the front of the main body part, and bank parts disposed on both sides of the back receiving part, protruding forward from both sides, and covering the front of the extending parts and side frame segments. A recess is formed at an area, facing a corresponding extending part of the extending parts, of a rear surface of each bank part.

Devices, systems, and methodologies for vehicle seats include selectively collapsible safety layers providing collapsible support to reduce impulse experienced by the seated passenger imparted by the vehicle seat, which can reduce the likelihood and/or extent of injury attributable to occurrences exceeding threshold momentum changes, such as transportation vehicle collisions.

An energy absorbing device includes a first connector and a second connector. The first connector is for connection to the base of a seat back of an aircraft seat and the second connector is for connection to the frame of an aircraft seat. The first connector is moveable relative to the second connector. The energy absorbing device further includes one or more resiliently deformable members which are compressed when the first connector is moved away from the second connector. Also described is a seat comprising the energy absorbing device and a row of seats.

A seat back (20) includes an upper thoracic support section (20a) for supporting at least a portion corresponding to a lower part of the upper thoracic spine of a seated occupant, and a lower thoracic support section (20b) disposed on a front side with respect to the upper thoracic support section (20a) and configured to support a portion corresponding to the lower thoracic spine of the seated occupant. The lower thoracic support section (20b) is configured to displace backward greatly, as compared with the upper thoracic support section (20a) in such, a way that the upper thoracic spine of the seated occupant is inclined forward, when backward inertia force acts on the seated occupant.

The object of the invention is to provide a vehicle seat which can improve degree of freedom in the design of the vehicle seat. A vehicle seat with a seat cushion and a seat back includes: right and left side frames 20 constituting right and left frames of the seat back; a pressure-receiving member 40 disposed between the right and left side frames 20 and configured to receive a load from an occupant; and a driving mechanism 50 disposed at each of right and left sides of the pressure-receiving member 40 and configured to cause a right end portion or a left end portion of the pressure-receiving member 40 to move from an initial position to an advanced position that is located frontward of the initial position or to move from the advanced position to the initial position, wherein the driving mechanism 50 includes a linkage (drive link member 100 and contact link member 200) configured to be connected to the pressure-receiving member 40 and a driving source 52 configured to actuate the linkage, and wherein the linkage is configured to operate when a load equal to or greater than a predetermined amount is input from the occupant to the pressure-receiving member 40 to cause the pressure-receiving member 40 to move to a backward position that is located rearward of the initial position.

[Problem] To provide a side airbag apparatus capable of quickly and properly restraining a passenger in the initial stage of deploying an airbag, along with a passenger protection apparatus including this side airbag apparatus.

[Resolution means] The airbag employed in the present invention includes: a first chamber (C1) which houses the inflator and is deployed outside in the vehicle width direction of the frame side wall part; a second chamber (C2) which is deployed inside in the vehicle width direction of the frame side wall part; and a gas guide (100) arranged so as to surround the inflator inside the first chamber. In addition, the first chamber (C1) is deployed such that at least a portion thereof, as seen from the vehicle side, overlaps the frame side wall part. A first inner vent is formed at the boundary part between the gas guide and the first chamber, with gas introduced from the gas guide to the first chamber via this first inner vent. Moreover, a second inner vent is formed at the boundary part between the gas guide and the second chamber, with gas introduced from the gas guide to the second chamber via this second inner vent.
